Frog Fanny substitute

Frog's Fanny is, imho, a great boon to the flat water fly fisher ( not so
flat, too ), but it is pricey.

I oscillate between wanting to support whoever is packaging it, because they
have improved my fishing and deserve support .... and wanting to find the
same stuff cheaper

I vaguely remember ( about the only type of remember I experience at my
age ) seeing something, somewhere, about the same material packaged for a
different market .... I'm not the least sure it was on ROFF, but if you know
of a different way to obtain this cool stuff ...let me know, please .....
and thank you, in advance
